More details on general Superdome complex tasks and features are
available in Chapter 3.
Local and Remote
Partitions
When you log in to HP-UX running on a partition, or when you access a
partition’s console, the partition you are accessing is considered to be the
local partition. All other partitions in the complex are considered to be
remote partitions whose resources you are not currently using.
You can manage and reconfigure the local partition while it remains
booted. To initiate some changes, such as adding or removing cells, you
must perform a reboot-for-reconfiguration.
In most cases you also can manage all other partitions in the complex
(the remote partitions) from your local partition. However, when you
perform some tasks on remote partitions, such as adding or removing
cells, the remote partition must be inactive (in a ready-for-reconfig state).
You can use the parstatus -w command to list the partition number for
the local partition.
Active and
Inactive Partitions
Each partition can be active or inactive, depending on its boot state.
A partition that is active is not in a boot-is-blocked state. It can be booted
to the Boot Console Handler (BCH) interface and can load and run
HP-UX.
# parstatus -w
The local partition number is 1.
